What is with the hype over Harry Potter 6?

Ok, so all over my facebook is friends talking about the midnight premier of HP 6. I'm sick of it because its a movie in which you already know what is going to happen if you read the book, and if you havent then your a moron. the movies have sucked since the 2nd, and its not worth a midnight showing nd the waste of 10 bux. my one friend tried to compare it to star wars and i said theyre wrong because with star wars, you didnt know exactly what is going to happen and that the author of the story had full insight into the movie and made all of them.
